Overview

SIWAREX FTA 3-3

3 Overview

3.1 General

SIWAREX FTA (Flexible Technology, Automatic Weighing Instrument) is a versatile and flexible weighing module which can be utilized wherever a scale should fulfill its tasks automatically. Automatic scale operation is characterized by a weighing procedure performed automatically according to a defined plan.

The SIWAREX FTA Getting Started software supports starting the setup of applications. Using the SIMATIC HMI control unit e.g. TP170B, a scale can be controlled by the operator. The software is open and provided with commentary, so that the user can change the software, expand it and easily modify it according to customer wishes.

For operation of more than one scale in a batch plant or for mixing, the SIWAREX MULTISCALE software is available, for operating more than one scale in bagging, filling or loading stations, the SIWAREX MULTIFILL software is available (see Accessories and Expansions 7).

3.2 Benefits

SIWAREX Getting Started has many advantages:

o Complete solutions for a scale

o can be used for autarchic or networked scales

o open and prepared for project-specific extensions

o SIWAREX FTA – integrated messages through ALARM_S

3.3 Application Range

SIWAREX FTA Getting Started is the optimal solution anywhere that direct weighing technology integration in the automation system is advantageous. Weighing is then a component of complex processes which are controlled by the automation system. Using the SIWAREX FTA software, calibratable weighing systems can be inexpensively constructed, whether they are filling systems, unloading stations, bagging operations or rotopackers.

Typical application ranges:

o Liquid Filling

o Bagging in a packaging plant

o Material unloading at an unloading point

3-4 SIWAREX FTA

3.4 Structure

The project is made up of two parts:

- STEP7 software for the SIMATIC CPU

- ProTool project (integrated in SIMATIC Manager)

The messaging system is also used. In this way the messages from SIWAREX FTA are displayed to the operator. In this message system (FB1, FC1) the messages are generated on the basis of ALARM S. Of course the customer can replace the message system with his own message system.

3.5 Function

The control of the weighing procedure is completely run from the weighing module as if in separately constructed weighing electronics. The integration in SIMATIC enables the progress of the weighing procedure to be influenced directly from the PLC program however. This way, there is sensible task distribution: the extremely fast weighing functions are handled in SIWAREX-FTA, the latching and signal linking is done in the PLC.

SIWAREX FTA Getting Started takes over the job of a standardized sequencing program in the SIMATIC S7. In SIWAREX FTA Getting Started, the scale FB is called, the commands and set values are handed onto the scales corresponding to the process status and the scale data is prepared for the visualization.

3.6 Commissioning- and Service with SIWATOOL FTA

SIWATOOL FTA is part of the scope of delivery of the configuration package SIWAREX FTA for SIMATIC S7 (order number 7MH4900-2AK01). To perform the commissioning, the program must first be installed on a PC. The PC and SIWAREX FTA are connected by the cable provided as an accessory.

Since not all SIWAREX FTA parameters can be set with SIWAREX Getting Started, the initial commissioning of the scale is handled with a PC and the SIWATOOL FTA program.

Using the SIWAREX FTA Getting Started program, the adjustment parameters (data record 3) and the basis data (data record 4) can be changed later and the scale can be adjusted afterward.

In dosing operation, the set value (data record 20) and the weighing parameters (DS22 and DS23) can be set with the TP/OP.

The interface parameters (data record 7) can only be defaulted and the optional MMC card only parameterized when commissioning with SIWATOOL FTA.

Commands

SIWAREX FTA 5-27

5 Commands

5.1 Command Groups

The SIWAREX FTA Getting Started software is parametered for operation with a one scale. The project is setup for the CPU 312C and TP170B.

5.2 Program installation in STEP7

First, the SIWAREX FTA module has to be installed in the HW config. Run the setup program from the SETUP_FOR_SIMATIC_S7 directory of the planning package SIWAREX FTA for S7 (order number 7MH4900-2AK01). Afterwards, you can find the SIWAREX FTA under the FM modules for the S7 300 system.

If you are using the same SIMATIC CPU 312C, you an simply load the module from the project into the CPU. The program can be run immediately afterward.

If you are using a different CPU, the hardware must be planned in the HW_Konfig first. The CPU 312C must be deleted first and replaced with the new CPU. When asked whether the program should also be deleted, enter "No".

Then transfer the program modules (FBs, FCs, OBs, DBs but not the SDB) to the module folder in the new CPU.

You are warned that the message block (FB1) must be generated again. Generating FB1 is done in the new project in OB1 as follows:

Delete the instancing data block of FB1 (DB1) and call the FB1 again. The generation of the new message numbers can then take several minutes.

5.3 Command Manager FC30

The commands of a scale are controlled by the appropriate function FC30. Using function FC30 the commands can be executed on the scale by three different job slots with different priorities.

CMD1 has the highest priority, CMD3 the lowest.

Calling the command manager is done in the OB1. The commands are actuated through various points in the program:

- by the operator at OP/TP with priority 2

- by time OB35 with priority 3

5-28 SIWAREX FTA

Priority 1 is not occupied.

CALL "Fc Execute command" ( iCmdInput := "DB_SCALE".i_CMD_INPUT, boCmdEnable := "DB_SCALE".bo_CMD_ENABLE, boCmdInProgress := "DB_SCALE".bo_CMD_IN_PROGRESS, boCmdFinishedOk := "DB_SCALE".bo_CMD_FINISHED_OK, boCmdErr := "DB_SCALE".bo_CMD_ERR, sCmd_1 := DB12.DBD 40, sCmd_2 := DB12.DBD 44, sCmd_3 := DB12.DBD 48);

Fig. 5-1 Calling the FC Command Manager

The input variable s_CMD1 contains the command code and the control bits for the command handling.

If FC30 is used as a Command Manager the commands may not be transferred directly to SIWAREX by calling the FB41 but by the structure CMD1, CMD2, CMD3.

s_CMD1 STRUCT Command input 1

i_CMD1_Code INT 0 Command code

bo_CMD1_Trigger BOOL FALSE Command trigger

bo_CMD1_InProgress BOOL FALSE Command in progress

bo_CMD1_FinishedOk BOOL FALSE Command finished ok

bo_CMD1_FinishedError BOOL FALSE Command finished with error

Fig. 5-2 Calling the FC Command Manager

5.4 Scale Call

Calling the FB_SIWAREX_FTA is done in the OB1. The FB is called with the following parameters:

Commands

SIWAREX FTA 5-29

CALL "SIWA_FTA" , DB 10 ( ADDR := 256, DB_SCALE := 12, DB_VECTOR := 11, CMD_IN := "DB_SCALE".i_CMD_INPUT, SIM_VAL := "DB_SCALE".r_SIM_VALUE, ANA_OUT := "DB_SCALE".r_ANALOG_OUT_VALUE, DO_FORCE := "DB_SCALE".b_DIG_OUTPUT_FORCE, TRANSITION := "DB_SCALE".b_TRANSITIONS, CMD_INPR := "DB_SCALE".bo_CMD_IN_PROGRESS, CMD_FOK := "DB_SCALE".bo_CMD_FINISHED_OK, CMD_ERR := "DB_SCALE".bo_CMD_ERR, CMD_ERR_C := "DB_SCALE".b_CMD_ERR_CODE, REF_COUNT := "DB_SCALE".b_INFO_REFRESH_COUNT, PROC_VAL1 := "DB_SCALE".r_PROCESS_VALUE1, PROC_VAL2 := "DB_SCALE".dw_PROCESS_VALUE2, SC_STATUS := "DB_SCALE".dw_SCALE_STATUS, ERR_MSG := "DB_SCALE".bo_ERR_MSG, ERR_MSG_TYPE := "DB_SCALE".b_ERR_MSG_TYPE, ERR_MSG_C := "DB_SCALE".b_ERR_MSG_CODE, FB_ERR := "DB_SCALE".bo_FB_ERR, FB_ERR_C := "DB_SCALE".b_FB_ERR_CODE, START_UP := "DB_SCALE".bo_START_UP_IN_PROGRESS, CMD_EN := "DB_SCALE".bo_CMD_ENABLE, ERR_MSG_Q := "DB_SCALE".bo_ERR_MSG_QUIT);

Fig. 5-3 Calling the scale in OB1

5.5 Alarms

The alarms for the scale are decoded with the FC1 and passed onto the FB1 for alarm generation with ALARM_S.

Alarm generation is supported by the systematics of the ALARM_S modules SFC18 and SFC19. In the indicated scope, the scale messages are monitored. Monitoring the display word INDW from the scale call using the FB_SIWA block is not integrated in the "Getting started" package.

! Note

When using the "Getting Started" package, ensure that after removing the display device e.g. TP170B from the system in online operation, no more alarms are generated. After connecting the des TP170B to the system again, the SIMATIC CPU must be started in RUN again.

Of course, the user can delete these program sections and use his own message system.

5-30 SIWAREX FTA

5.6 Configuring with ProTool

The software is setup for the display of a scale in TP170B.

The conversion to other SIMATIC HMI devices is possible.

ProTool offers a selection of target devices for the conversion.

5.7 Program installation in ProTool

If you are using the CPU 312C and TP170B, the program is immediately ready for operation after loading onto the TP170B. When loading via the MPI interface, use the MPI address=1 for the TP170B, for the CPU MPI address=2.

5.7.1 Setting up the calibratable display

For displaying the calibratable weight value, the same device that the operator uses for running the system can be used.

The calibratable main display for one or more scales can be one of the following devices:

TP170B, OP170B

TP270, OP270, MP270B

MP370

The SIMATIC HMI device can be connected with the MPI or to PROFIBUS. The calibratable display of the weight value can be connected in any system hierarchy. The connection does not have to be sealed and future planning for operator windows are also not influenced by the calibratable weight display.

5.7.2 Function of the Calibratable Weight Display

The value for the calibratable weight display is generated internally by the SIWAREX FTA, it is encoded and then provided in the data record DS 35 for the user.

The DS 35 data record is read by the FB SIWA_FTA and is put in the scale DB just like every other data record in a defined address.

The content of the DS 35 can be sent via the bus connection to other SIMATIC-CPUs or it can be evaluated locally.

For the evaluation, an AddOn is used for ProTool – a special function, which is able to decode the contents of the DS 35 and display it in a special output field. This AddOn is called "Assured Output" and must be installed in addition to ProTool.

Commands

SIWAREX FTA 5-31

Fig. 5-4 Display of the Calibratable Display in TP/OP

5.7.3 Installation and Setup of the Calibratable Weight Display

First, the OCX for the assured output must be integrated into the setup environment of ProTool. This is possible with version 6.0 SP2 ProTool(Pro) or higher.

That program that can perform the installation can be found in the OCX_DISPLAY directory of the planning package.

If ProTool is not on drive C: or D:, the setup.bat program must be edited with an editor and written to the other drive.

After executing the setup.bat program, the Prootool.ini file must be changed according to the note in setup.bat.

5-32 SIWAREX FTA

Fig. 5-5 Function "Assured Output" in ProTool

If ProTool is called again afterwards, a new function appears in the tool-bar (see arrow) - "Secure output", which is projected just as all other functions.

During planning, the address of the data record DS 35 must be defined. The variable is BYTE and has a length of 32 bytes.

The refresh rate lies somewhere around 200 to 300 msec which is comfortable to the eye.

Note

After converting a project to another target device, the assured output must be deleted in the images and planned again.

! Note

When loading the project to the target device, a notice can be displayed which indicates that the OCX is not certified. This notice has no influence on the functionality of the AddOn.

Commands

SIWAREX FTA 5-33

5.7.4 Planning another CPU

If you are using another CPU, the project must be integrated into the new environment.

Select the controller from the Controllers menu in ProTool and link the controller for the communication with the OP/TP in the Parameter menu.

Then, activate the Restore symbol in the Edit menu.

In the last step, the project must be loaded to the target OP/TP.

5.7.5 Planning another TP/OP

If another SIMATIC-HMI device is used, the project must be integrated into the new environment.

After activating the menu for the project conversion, you are presented with a list of possible target devices. Select the device from the list and perform the conversion.

The following procedures are handled as they are when using a new CPU – see Planning another CPU 5.7.4.

! Note

When converting in TP/OP270 or 370, the calibratable display must first be deleted and then setup again in the Main_Scale_Screen_2 image. See Setting up the calibratable display 5.7.1.
